That title may make my spam-comment filter work overtime. Anyway, this post continues the discussion of managing figure in wood. Let’s look at the orientation of the annual rings in the rectangular blanks from which curved legs will be cut. Short sections of Douglas fir will be used to illustrate the principles.

All of this refers to legs which curve in three dimensions (planes). The curves may be cut on all four faces (e.g., a cabriole leg) or just two adjacent faces. Legs in which the curves are cut only on two opposite faces are curved in only two dimensions (picture the leg sandwiched between two flat sheets of plywood) and are a somewhat different matter. Bent lamination legs are an entirely different matter. Please do not ask me about legs which alter the time-space continuum.

The photo above shows the three possible basic orientations. The dot on the end grain indicates the inside corner of the legs. The two faces adjacent to this corner usually each have a flat portion where the aprons are attached with mortise and tenon joints.

In the three legs, from left to right, consider the endgrain patterns:

• The annual rings are approximately parallel to one face and perpendicular to the other, producing one flatsawn face and one quartered face.
• The annual rings are approximately 45° to all four faces and run “across” the inside corner.
• The annual rings are approximately 45° to all four faces but run parallel to an axis from the inside corner to the outside corner.

For simplicity, I cut the curves into two adjacent faces. The effects would be the same if curves were cut into all four faces such as in a cabriole leg.

Let’s look at the results.

The leg on the left is bad news. The irregular figure produced by cutting a curve into the flatsawn face is unpleasant in itself, and the inconsistent figure among the faces distracts from the shape of the leg.

The middle leg is an improvement but, to my eye, the figure lines fight the curves of the legs. There is too much run-on and run-out of the annual ring lines.

I like the leg on the right. By cutting the blank from approximately 45̊ riftsawn stock and orienting the growth rings in this way relative to the inside corner, a good lookin’ leg arises. The shape of the leg (though uninteresting in this example) coordinates with the figure.

Here are closer views: 

Note that another disadvantage of the leg on the left is the exaggerated consequence of a small knot intersecting the cut line. Small pin knots, such as are common in cherry, can be difficult to avoid, but the middle leg demonstrates that they will have much less consequence with that grain orientation.

It is hard to find a thick, purely riftsawn board from which to make leg blanks, but most fairly wide flatsawn boards contain some effectively riftsawn stock toward the sides. I examine the end grain and face grain and carefully select the best sections of such boards. I pay attention to the straightness of the figure along the length of the board, recutting the edge to “straighten” the figure lines if necessary. I also try to somewhat coordinate bends in the figure with bends in the leg design.

Of course, you can choose however you like to use figure, but the key is to be aware of it and manage it. Making your design and the beauty of the wood work together, each enhancing the other, can bring class, beauty, and quality to your woodworking projects.

Happy woodworking to you.

Wood has figure that was created from life, which, in turn, helps bring life to a creation in wood. Throughout designing a piece, choosing wood, and building, I want to make the most of what the wood has to offer so a synergy develops between the design and the wood. This is not aluminum, Corian, or clay upon which a design is imposed; this is wood!

When cutting curves in wood, it is helpful to predict how the figure will change. The figure should work with, not fight, the contours of the piece. The interpretation of that task is subjective but it pays to be aware of and work skillfully with the figure. (Bent lamination, by the way, is a different matter.)

Here is a visual guide to some of the issues that arise in curved work. I used home center Douglas fir which has obvious figure lines created by the large difference between the earlywood and latewood. This is for purpose of illustration, it is not meant to be pretty.

In the photo above and the next two below, a concave curve (marked on the top surface) cut into the rift face causes the figure to bend. The end grain is emphasized with pen lines to show that the annual ring lines go downward as you go deeper into the wood. Thus, the concave curve creates a smiley bend from the straight face. A convex curve would do the opposite. 

Below is the result if we started with the block with the opposite face on top. (I just turned the same block upside down.)

Now let’s cut a similar curve into a nearly-flat-sawn face. The end grain lines meet the face at an extreme angle and so the figure changes rapidly as we cut the depth of the curve. The result is, to my eye, unattractive. Some of the figure lines run off the resultant face at the bottom and jump on at the top.

Now let’s cut the curve into the quartered face. Since the annual ring lines meet the face at about 90̊, there is almost no shift in the direction of the figure after the curve is cut. 

Of course, many other variables come into play, including the depth and consistency of the curves, and their placement in the piece. None of this would matter much in basswood which is nearly absent in figure.

The main ideas:

• appreciate that the figure changes as curves are cut into wood
• it is helpful to be able to generally predict how the figure will change
• use this to the best advantage of the wood and the piece you are making.

Next, we’ll look at how this applies to curved legs. The appreciation of figure and legs, now there’s a worthwhile topic.

1. Be a control freak

Once a machine woodworking procedure starts, any unexpected event will occur suddenly, probably too quickly for you to react. At that point, your defense is whatever margins of safety, such as guards and hand clearances, that have been built into the setup and come into play after the mishap. You have to hope they are adequate to prevent injury.

The safest way to use a woodworking machine is to know, before starting, exactly what is about to happen. It should be a completely predictable operation. We know the machine itself will operate in a fully predictable manner (the blade or bit spins), and so your job is to thoroughly understand and control the interactions among you, the wood, and the machine. You must understand all the forces at work. In short, don’t hit the start switch if your mind harbors doubts!

Of course, still use the guards and clearances.

2. Cut or throw?

A machine blade or cutter, given the opportunity, will always throw the wood rather than cut it. You must deny the machine that opportunity by restricting the movement of the wood, and ensure that it has the capacity to cut the wood. Using hand-held power tools, it may be the tool itself, with your hands still holding it, that gets kicked.

All of the following mishaps, among many more, are essentially a cutter throwing the work piece because the operator gave the machine an alternative to cutting it:

• Table saw kickback – the absence of a splitter/riving knife allows the kerf to pinch the rising blade which grips and violently throws the wood.
• Thickness planer kickback – a short board is freed from the infeed roller before reaching the outfeed roller so the blades grab and eject the unrestricted wood.
• Drill press – the rim of a bit, such as a large diameter Forstner, snags an unclamped work piece and throws it, or worse, pulls in the hand that is trying to hold it. Re-entering a hole with a spinning bit increases the chance of this disaster.
• Bandsaw – wood held above the table surface is presented to a coarse tooth blade and gets slammed to the table, drawing the worker’s hands with it, possibly into the blade.
• Router table – uncontrolled climb cutting (feeding the work piece in the direction of the cutting edge rotation) zooms the wood across the table, possibly carrying the woodworker’s hands into the cutter.

Well, I’m getting uneasy just writing these scenarios. Of course, these two concepts are just part of safe practice, and there are many more ways to get hurt with machines. However, keeping these two basic principles in mind – and in action – will go a long way toward using machines safely.

Stay safe in the shop!

When I want an absolutely reliable reference measuring tool, I reach for a Starrett. It’s that simple.

We’ve all had our frustrations with tools that seemed promising when new but proved to be deficient in design or construction and thus do not perform. I particularly avoid tools that are unnecessarily complicated or are merely solutions chasing a problem. Worst of all are tools that are made just to be pretty. On the other hand, don’t get me wrong, there are some great small-scale toolmakers out there making high quality, useful, and often innovative products.

Reliable primary references for straight and square are necessities in the shop – specifically, a straightedge at least 24″ long and a combination square (a large machinist square is a more expensive and less versatile alternative). Don’t skimp on quality for these; they are lifetime tools. Get Starretts and be done with it. (A flat reference, such as a granite surface plate, though not a must, is also helpful and can be had economically.) My Starrett tools include a 24″ straightedge, a combination square with a hardened head and 12″ and 18″ blades, a 6″ adjustable square, and several others that would be considered more optional than basic.

The integrity of most shop procedures and tools can be traced to verifications using these reference tools. Examples are a flat jointer table with a square fence, the soles of handplanes, a table saw crosscut jig, shop-made jigs, and so forth. Things such as these allow you to start a project on a reliable basis rather than dealing with fundamental inaccuracies that will be carried like an infection through the building process.

Top grade straight and square reference tools are like the Constitution of your shop and you’re the Supreme Court.

Starrett is a solid American company with a proud history, and is technologically current and innovative. They continue to manufacture most of their precision tools at their Athol, Massachusetts plant, working to unsurpassed tolerances. Every one of their measuring tools that I own or have seen has been exquisitely well finished. A Starrett is a mensch at the bench.

Here is some help with pencil lines on dark wood. Though knife lines can be modified to produce the advantage of a physical feel for the correct location of a tool such as a chisel, most layout in woodworking is done with pencil lines. Marking out the tails for tails-first dovetailing and curved layout lines for bandsawing are examples.

Graphite pencil lines have a bit of sheen which helps their visibility but I still find them difficult to see, particularly if the line is along the grain on a wood like Claro walnut, which is dark and has color variations. So, motivated particularly by my love of Claro, I have experimented with various white or light-colored pencil and ink lines.

I tried Japanese ink “brushes” and very fine point drafting pens. I do not like marking out in ink because I do make mistakes and have no immediate plans to cease, so no ink for me.

I have scoured art supply stores and experimented over the years with various white pencils, occasionally trying bright yellows and other colors. Most are too soft to retain a sharp point for a practical amount of work.

The best pencil I have found is the Sanford/Prismacolor Verithin White #734. It can be sharpened to a point that is nearly as sharp as a #2/HB graphite pencil. It wears faster than a #2 but the point holds up well enough, especially if used with a light touch. It makes a nicely visible line on walnut. It is not as easily erasable as graphite, but decently enough using a white “plastic” eraser. They cost from 39 cents to a dollar apiece, depending on the quantity and the store.

The top photo shows sets of three lines of #2/HB graphite and #734 White going across and along the grain, made from a single sharpening of each pencil. The graphite lines along the grain are barely visible just above the white lines. The photos below show the same lines photographed from different angles.

An alternative is a white 0.5 mm mechanical pencil refill stick made by Pergamano and available from McAllister’s. I have not tried these because they cost $10 for 10 sticks and I would be concerned that they would break easily. Also, the point of the Prismacolor pencil can be easily altered using sandpaper. This is a more fussy job with a less durable result using 0.5mm lead.

No matter what instrument is used for layout, visibility and accuracy are greatly enhanced by using proper lighting. The two simple rules are strong and adjustable. Strong mostly means close, and the light source must be moveable to avoid glare and to cast shadows only in favorable locations. Every effort should be made to set up good lighting.

White #734 sharpened, I’m ready to indulge in Claro.

I usually approach the completion of a project with hesitancy because I know that, for better or for worse, this is as good as the thing is going to be. I no longer can do anything to improve it, except for marketing, and must accept it. Competing with this is the sense of wanting to get the damn thing out of the shop because I’ve already put enough sweat into it.

Another, more important, very distinct, feeling comes over me. Readers, maybe you can relate. I have a sense of separation from the piece. It is now out of my hands and has a life of its own without any further influence from me. It feels almost as if someone else might have made it.

Well, isn’t that the point of creativity, to make something that stands on its own and is appreciated for what it is apart from its maker? Yes, attention is rightfully now on the object, not its maker. People will, to varying degrees, like or dislike the object. The object is not you, so don’t take the praises or winces too personally. Even though you made it, in this sense it’s not yours anymore and doesn’t need you. Hopefully, it will even outlive you.

This view is in contrast to that of the painted, pierced chic “arteests” of today who seem to prefer that everyone dwell on them more than on what they have made. I believe that we as artists (artisans, craftsmen, woodworkers, whatever you prefer) should be humbled by the degree of mystery that lies in making things.

Yes, this work is personal, but consider the words of James Krenov, “. . . the worth of such things is their whole content . . . [to be] seen – and lived with, in a coming together of sense and observation that will bring quiet joy long after the maker is forgotten.”

It is good to build good things.

These thoughts started to gel as I was browsing a craft exhibit of many wonderful pieces. There were also a few that didn’t quite measure up, at least in one man’s opinion. I wondered what, apart from preferences in style, had formed my view of an object as a creative success or as falling short.

Further, I supposed these considerations could help me with my work. “I work wood, therefore I am??”

At the core of creativity is the development of a powerful, compelling, rich idea. By “idea,” I mean more than a whim or an attractive notion. I mean a driving, guiding force with enough energy to result in a creation. I like the word “concept” for this. Without it, a creative effort really doesn’t stand a chance.

When designing a new piece, I wonder why would anyone, including me or a client, really care about this. One way out is to make ostentatious nonsense or to be different for its own sake. No, I want to make refined work that elicits the “quiet joy” of which Krenov wrote.

Moving ahead, a clear concept produces economy of intent and execution. The artist/craftsman grasps the essence of what he desires to create, and thus driven, marshals the skills and focus to make it be. To get the job done, the intent must coordinate with workmanship and this must be conscientiously sustained throughout the construction process. In other words, consistency of intent should engender consistency in workmanship so that one reflects the other.

OK, nice lines on paper that I’ve got here but I better be able to pull this off. I must have the skill and mental focus to carry this through because no one puts up scale drawings in the living room.

The result of all of this, we hope, is harmony of all the aspects of the piece – form, wood, color, details, and so forth. This is pleasingly evident when viewing the piece. It is so readily evident that it will likely make the viewer blissfully unaware of the sweat it took to get to the final product.

By contrast, inconsistency and disharmony are readily evident. Think brown shoes with a tuxedo (inconsistent intent) or a suit that would look great except for an awkward fit that can’t be ignored (inconsistent workmanship).

I better be clear about where I’m going with this because I’m going to invest a lot of work in it. More than hope that it will “come out good,” I’ve got to think and believe that it will.

More than merely theoretical meanderings, this is the stuff that makes a piece produce that good “Ahhh” feeling. It is a formidable job to have a good idea, recognize and develop it, then sustain it as you execute it with consistent workmanship. I am grateful to be able to make things in wood, it is fun, and at times exhilarating, but I do think it is truly difficult to do well.

Stay with it, you can do it. “Unity and variety,” as Maestro Heath used to say.

As discussed in the previous post, one of the keys to successful work with the jack plane is the use of a vigorous diagonal stroke. To stabilize the board from the pressure in multiple directions, I like to use Veritas Bench Pups, Bench Anchors, and Wonder Pups in various configurations, usually along with regular bench dogs, as shown in the photo above. Other options for use of these handy devices and shop-made stops at the right and left sides of the workbench are discussed in these two earlier posts.

Beware when planing thin boards, say under ½”, which can flex. It may be necessary, for example, to place shims, such as blue tape or veneer, under a convex surface facing the bench for a similar reason that you would not place a non-flat surface on a thickness planer machine bed. Likewise, it is often necessary to place shims under the high corners of a twisted board.

To set the blade projection, I use these steps: I sight from the front of the sole, with light adjusted to reflect off the thin flat at the rear of the mouth (I file that flat when I set up a new plane). I advance the blade enough to see it to correct the lateral adjustment, then back off the projection to a minimal amount. I start stroking the plane on the wood, back and forth, gradually advancing the blade, often using my left hand on the feed screw and my right on the tote. I’ve found this method gives better results than using sight alone, or running a narrow scrap against the blade.

The long infeed length of the Veritas BU jack makes it feel almost like a jointer. It’s easy and natural to move the plane back and forth rapidly without lifting it, like scrubbing the wood. This gives excellent tactile feedback to be able to sense when the surface is approaching flatness.

The Veritas BU jack has some other nice features. The lack of a cap iron (“chipbreaker”) makes swapping blades very easy. I find the little set screws on each side of the plane near the mouth help to quickly position the new blade. The mouth opening can be adjusted in seconds to accommodate different shaving thicknesses. This is far easier than adjusting the frog on a bevel-down plane. I also like the Norris-type combined feed and lateral adjustment mechanism, though some woodworkers do not.

I strongly suggest getting rid of the awful handles that Veritas puts on their planes and get a set from Bill Rittner – I think you will find that they dramatically improve the feel of the plane.

These features make the Veritas BU a good choice for your workhorse jack plane. That said, I also have a 30-year-old Record #5. They each have their advantages, I use both of them regularly, and will not be parting with either. If you want me to declare a winner, I can only say that there’s more than one good way to do most everything in woodworking. I hope these posts will help you find your way.
